Continental Contitech 20042104 V-belt Section B 89in B86

Product Description

The CONTINENTAL CONTITECH 20042104 is a Section B V-belt rated for heavy-duty power transmission in industrial and HVAC drive applications. Built with Wingprene rubber-impregnated fabric, this belt delivers oil and heat resistance suited for demanding environments. It carries an outside length of 89 inches and an internal length of 87.80 inches, fitting standard B-section sheave grooves. The HY-T Matchmaker construction maintains consistent tension across matched sets, reducing vibration and uneven wear on drive systems. Licensed technicians and maintenance professionals install this belt in belt-and-sheave assemblies on air handlers, fans, blowers, compressors, and general industrial equipment.

This belt is designed for use in HVAC air handling units, commercial ventilation systems, industrial blowers, and general-purpose power transmission drives that use B-section sheave configurations. The Wingprene material provides resistance to heat, oil, and static buildup, making it suitable for both indoor mechanical rooms and light outdoor equipment enclosures. Its operating temperature range spans from -40 degrees C to 140 degrees C, allowing use in cold-start and high-heat environments. The B86 designation aligns with industry-standard belt numbering for cross-reference and replacement sourcing.

Installation Notes

Installation is performed by qualified HVAC technicians or industrial maintenance personnel. De-energize and lock out the drive system before removing the old belt or installing the new one. Never pry a V-belt over sheave flanges with sharp tools, as this can damage the belt cords and reduce service life. After installation, verify sheave alignment and confirm proper belt tension before returning the unit to service.
